1M Cermet Trimmer Potentimeter (Pack of 5) - Pinout Explanation and Connection Guide
The 1M Cermet Trimmer Potentiometer is a variable resistor used to adjust signal levels in electronic circuits. It consists of a rotating shaft that varies the resistance between the input and output terminals. In this documentation, we will explain the pinout of the 1M Cermet Trimmer Potentiometer and provide a connection guide.
Pinout:
The 1M Cermet Trimmer Potentiometer has 3 pins, labeled as follows:
Pin 1:
Terminal 1 (T1)
Function: One end of the resistive element
Connection: Typically connected to the input signal or voltage source
Pin 2:
Wiper (W)
Function: The moving terminal that varies the resistance between T1 and T2
Connection: Typically connected to the output signal or load
Pin 3:
Terminal 2 (T2)
Function: The other end of the resistive element
Connection: Typically connected to ground or a fixed voltage reference
Connection Structure:
Here is a step-by-step guide to connecting the 1M Cermet Trimmer Potentiometer:
1. Connect Pin 1 (T1):
Connect the input signal or voltage source to Pin 1 (T1). This can be a voltage source, a signal generator, or an output from another circuit component.
2. Connect Pin 2 (Wiper):
Connect the output signal or load to Pin 2 (Wiper). This can be a LED, a transistor, or any other component that requires a variable voltage or current.
3. Connect Pin 3 (T2):
Connect Pin 3 (T2) to ground or a fixed voltage reference. This sets the upper limit of the resistance value.
Tips and Precautions:
When adjusting the potentiometer, use a screwdriver or a Similar tool to turn the shaft. Avoid using excessive force, which can damage the component.
The 1M Cermet Trimmer Potentiometer is a variable resistor, so it can be used as a voltage divider, signal attenuator, or impedance matcher in electronic circuits.
Ensure that the current flowing through the potentiometer does not exceed the rated current handling capacity to prevent overheating and damage.
By following this pinout explanation and connection guide, you can effectively use the 1M Cermet Trimmer Potentiometer in your electronic projects and circuits.

Example 1: Arduino Voltage Divider

In this example, we'll use two 1M Cermet resistors to create a voltage divider circuit to measure a voltage signal using an Arduino board.

```c
const int inputPin = A0;  // Analog input pin
const int outputPin = 9;  // Digital output pin

void setup() {
  pinMode(inputPin, INPUT);
  pinMode(outputPin, OUTPUT);
}

void loop() {
  int reading = analogRead(inputPin);
  int voltage = reading  5.0 / 1023.0;  // Convert analog reading to voltage

// Use the voltage divider formula: Vout = Vin  (R2 / (R1 + R2))
  int dividerOutput = voltage  (1000000 / (1000000 + 1000000));
  analogWrite(outputPin, dividerOutput);
  delay(50);
}

GPIO.setmode(GPIO.BCM)

led_pin = 17
resistor_pin = 23

GPIO.setup(led_pin, GPIO.OUT)
GPIO.setup(resistor_pin, GPIO.OUT)

try:
    while True:
        GPIO.output(led_pin, GPIO.HIGH)
        GPIO.output(resistor_pin, GPIO.HIGH)
        time.sleep(1)
        GPIO.output(led_pin, GPIO.LOW)
        GPIO.output(resistor_pin, GPIO.LOW)
        time.sleep(1)

const int resistorPin = 33;  // Digital output pin

void setup() {
  Serial.begin(115200);
  pinMode(sensorPin, INPUT);
  pinMode(resistorPin, OUTPUT);
}

void loop() {
  int sensorValue = analogRead(sensorPin);
  float voltage = sensorValue  3.3 / 4095.0;  // Convert analog reading to voltage

// Use the voltage divider formula: Vout = Vin  (R2 / (R1 + R2))
  float dividerOutput = voltage  (1000000 / (1000000 + 1000000));

Serial.println("Sensor voltage: " + String(voltage) + "V");
  Serial.println("Divider output: " + String(dividerOutput) + "V");
